Hi UG friends. I have a bit of a problem I could do with some advice on before I take my stuff to the local guitar shop. I have a Peavey Bandit 112 combi amp, and got a Trace Elliot 2x12 cab to beef it out. Problem is, when I plug from the speaker out on the Peavey into the speaker, nothing happens. Sound still comes out of the amp, but nothing from the speaker. This is my first speaker cab, and I'll admit I don't fully know what I'm doing. I checked the impedances though, and they are both 8 ohms, so where lies the problem? Any help would be greatly appreciated. Cheers.

I'm not 100% positive about this, but I'm pretty sure that when you plug a cab into that amp it is supposed to disengage the internal speaker.

If this is the case, that tells me that your jack might be, well, jacked up. Try plugging the cable in without the cab connected to the other end and see what happens. If the internal speaker goes quiet, the cab is jacked, if it doesn't, the jack is jacked.

Or something like that...

Isn't Trace Elliot bass gear..?


not all. i have an (late 90's? ) speed twin combo that isn't bad. you can scoop them up cheap.

The internal speaker is supposed to play along with the ext cab. Could be the extension cab jack. You arent plugged into the preamp out are you? If the cab reads 8 ohms, that should all be working. Could be the cable. If the ext jack is functioning the other end of the cable should have some ac volts to read on the voltmeter.

do tell me you are using a speaker cable and not an instrument cable, right???

Haha an instrument cable will make sound in the cabinet but everything will get hot and eventually destruct.

Yes I am using an instrument cable (just for the mean time while I test stuff).


How hot does it get? lol

flat out - you NEED a speaker cable.

If you're saying that the Trace Elliot cabinet has a pair of 8 ohm speakers in it, you have a 4 ohm cabinet, and the minimum impedance for the extension speaker has to be at least 8 ohms. What model 2x12 is this? Old one? And you're plugging into the extension speaker hole and not the preamp output or the FX output, right?

(The silver stripe bandit at least) is actually a 4 ohm amp. It runs on an 8 ohm internal speaker 80watts and with the ext speaker hooked up, runs 2 8 ohm speakers for a total of 4 ohms 100watts. I just replaced my internal speaker. I swear it was 8 ohms when i put it in last year, but it reads 4ohms now. So ive been running a 4 ohm load plus a 8 ohm ext cab for a year now. I also ran the ext cab with an instrument cable for years before trashed scolded me for it hahaha. I think this guy has a prob with his jack. Unplugging the internal speaker and holding the leads onto the ext speaker cable will tell for sure. Making sure not to touch the leads together, that would be death for the amp right?

haha. that is one thing i always mention.

i have seen two amps die from this in person in my time. one was a guitarist i used to play with, and the other was a band i opened for. if they would have been smart enough to figure out what is wrong and turn it off, they would have been fine replacing the cable, but in that scenario, they were fucking with the knobs and volume. ahhhh. burning smell. and burning wallets.

rant aside, yeah get a speaker cable.

______

the best thing to do would be to take the leads off of the speaker and read the impedance (ohms). check the cab impedance.

connect the lead off of the amp going to the speaker to the cabinet (assuming both impedences are the same), and see what happens. you should get sound just like the sound that was coming out of the combo (different because of different speakers which is relatively obvious). if it is the same then the switching is messed up on the jack that goes to the cab.

i would have to take a look at pics or a schem to figure out if the jack is a switching jack. keep in mind i am a newer tech, just at it a few years, not like some of the guys on here who are full EE's. (i have an MBA and am studying some electronics stuff at the moment).
